目的讨论阿莫西林联合果胶铋治疗慢性萎缩性胃炎的应用情况及对表皮生长因子受体的影响。方法选取我院慢性萎缩性鼻炎患者100例,将其分为实验组和对照组。对实验组患者给予阿莫西林联合果胶铋治疗,对对照组患者给予传统方法即应用抗生素进行治疗。结果接受治疗后,实验组患者的有效率高于对照组;实验组患者副作用的发生率低于对照组。实验组的效果明显优于对照组。结论阿莫西林联合果胶铋在慢性萎缩性胃炎患者中的应用良好,增强表皮生长因子受体。对治疗该病有良好的作用,可推广至临床中。 Objective To discuss the application of amoxicillin combined with pectin and bismuth in the treatment of chronic atrophic gastritis and its effect on epidermal growth factor receptor. Methods 100 cases of chronic atrophic rhinitis in our hospital were selected and divided into experimental group and control group. Patients in the experimental group were given amoxicillin combined with pectin bismuth, and patients in the control group were treated with antibiotics by the traditional method. Results After treatment, the experimental group was more effective than the control group; the incidence of side effects in the experimental group was lower than that in the control group. The experimental group was significantly better than the control group. Conclusion Amoxicillin combined with pectin bismuth in patients with chronic atrophic gastritis in good use, enhanced epidermal growth factor receptor. The treatment of the disease has a good effect, can be extended to the clinic.
